# How to Vibe Code Your Own Mixo (and Stop Paying for It)

> AI Website Builder for Small Business

- Site: https://mixo.io
- Category: Web Application
- Verdict: **Solid side project** (75/100 vibecodeable)
- Estimated effort: 2-3 weeks part-time

## Verdict

Build a personal subset for fast landing page prototyping, but keep paying if you need multi-tenant custom domains and automated SSL at scale.

Vibecoding an AI landing page generator with Next.js, Claude, and Tailwind is straightforward over a few weekends. The real friction points will appear when attempting to replicate automated wildcard DNS routing, dynamic SSL issuance for custom user domains, and high-concurrency LLM parsing without timeouts. For personal use as a rapid wireframing tool, building a local generator is a fun project; for production multi-tenant hosting, the modest monthly fee saves massive infrastructure headaches.

### What you can't replicate

- Proprietary user base of hundreds of thousands of active creators
- Global edge infrastructure with automated zero-config custom domain provisioning

## What it does

An AI-powered website builder that generates complete landing pages, copy, images, and lead capture forms from a single text prompt.

### Core features

- Natural language prompt to website generation (layout, copy, images)
- Visual section-based block editor for client-side text and styling adjustments
- Automated contact and waitlist form builder with spam protection
- Subscriber management dashboard with CSV export
- Automatic llms.txt and llms-full.txt generation for AI search optimization
- Global content network deployment and hosting

## The business

### Pricing

- Free Plan: Free — One-page site published on a Mixo subdomain with branding.
- Basic Plan: ~$9/mo — Intended for single-page sites with custom branding removal.
- Growth Plan: ~$19/mo — Multi-page support for growing businesses.
- Premium Plan: ~$39/mo — Unlimited pages and advanced injection capabilities.

Founded 2022.
Team size: Small boutique team.

## The hard parts

- Multi-tenant dynamic custom domain mapping and automated SSL provisioning
- Reliable structured JSON output generation from LLMs for diverse business templates
- Global CDN caching layer for instantly published landing pages

## How to vibe code Mixo

### Prerequisites

- Node.js (free): Required runtime for modern full-stack TypeScript web development.
- GitHub (free): Code repository hosting and seamless integration with deployment platforms.

### Recommended AI tools

- Claude Code: Executes complex multi-file scaffolding and full-stack iteration directly in the terminal.
- Cursor: Provides an AI-native code editor to inspect visual component diffs and fine-tune Tailwind styles.

### Stack

- Frontend: Next.js
- Backend: Next.js API Routes
- Database: Turso
- Auth: better-auth
- Payments: Stripe
- Other: Vercel AI SDK, Tailwind CSS, Resend

### Hosting

- Vercel (Hosting the Next.js frontend and serverless API endpoints with zero-config preview deployments.): $0-20/mo
- Cloudflare (Global edge caching, DNS management, and security proxying.): $0/mo

### Build guide

1. **Project Scaffolding and Database Schema** — Initialize the Next.js app with Tailwind CSS, configure Turso for SQLite storage, and set up better-auth tables.

```
Create a new Next.js project using App Router, TypeScript, and Tailwind CSS. Configure Turso as the database driver using Drizzle ORM. Define database schemas for 'users', 'sites' (id, userId, title, description, contentJson, subdomain, customDomain, publishedAt), and 'submissions' (id, siteId, email, message, createdAt). Implement better-auth for user authentication with email and password. Ensure all TypeScript types are fully exported and strict mode is enabled. Verify database connection scripts run cleanly.
```

2. **AI Generation Pipeline** — Implement the core prompt-to-website generation engine using the Vercel AI SDK and Anthropic API.

```
Implement an API route in Next.js using the Vercel AI SDK and Anthropic API that accepts a natural language business description. Use structured object generation to return a strict JSON payload representing a complete landing page structure: hero headline, subheadline, features list (title, description), call-to-action text, and color palette preferences. Handle API timeout edge cases, validate the schema with Zod, and save the generated site payload directly into the Turso database linked to the authenticated user.
```

3. **Visual Block Editor UI** — Build an interactive client-side WYSIWYG section editor for tweaking text, swapping images, and adjusting styles.

```
Build a responsive visual site editor page in Next.js App Router where users can click on any section of the generated landing page (hero, features, form) to edit inline text, modify color variables, and select stock images. Ensure changes update local React state instantly and provide a 'Save Changes' button that persists the updated JSON content structure back to the database backend API route.
```

4. **Form Capture and Subscriber Dashboard** — Create public lead capture form handlers and a private dashboard for reviewing submissions.

```
Create a public-facing dynamic landing page renderer that reads published site JSON configurations from the database and renders clean Tailwind markup. Include a fully functional contact/waitlist form with built-in client-side validation and anti-spam Honeypot fields. Wire the form submission to a backend API route that stores entries in the 'submissions' table, triggers an optional Resend notification email, and displays a success message. Build a protected dashboard page allowing users to view, filter, and export their site's form submissions as a CSV file.
```

5. **Automatic llms.txt Generation and Publishing** — Implement dynamic generation of llms.txt and llms-full.txt files for AI search engine optimization.

```
Implement dynamic API routes for published sites that automatically generate and serve an 'llms.txt' file (providing a concise markdown table of contents with links to page sections) and an 'llms-full.txt' file (containing the complete markdown text representation of the site content) following the official llmstxt.org specification whenever a site is published or updated.
```

### Cost vs paying

**Starting costs (one-time):**

- Domain name (optional): $12/yr
- Total: ~$12 one-time

**Ongoing costs (monthly):**

- Vercel / Cloudflare hosting: $0/mo
- Anthropic API credits for AI site generation: ~$3-5/mo
- Total: ~$5/mo

- Paying for the SaaS instead: ~$19/mo (Growth Plan)
- Build time: 25-35 hours
- AI tool credits: $20 (Claude Pro / Cursor)
- Break-even: Not financially rational; build for learning and custom control.
